Tom worked up the cores Schulman collected sometime around 2010, and discovered the tree's age at that time.

For a crossdated age, there should be no question of the age of the portion of the tree sampled, except in any portion of the ring series not confidently crossdated with either other trees at the same site or other sites in the area.

Ring-counted ages are derived by simple ring counts and may contain errors in age due to missing or false rings, suppressed areas, poorly surfaced samples, or other types of tree-ring anomalies (e.g., injuries).
